Found small purple pill

Found a small, round purple pill with a "V" (or possibly an "A") on one side and "30" on the other in a family member's purse. Anybody know what this might be? Also, there was aluminum foil with burn marks, perhaps whatever it is can be burned or smoked.

Im on Morphine Sulfate 30mg (M S Contin)Its the only thing that I know that is small round and purple.
It has a M on one side and 30 on the other, its a timed release pill, maybe someone scratched off the coating partialy, making it look like it says a different letter.
